	  Configures the heap size for dynamically allocating the regions for
	  storing status FIFO and control FIFO words which will be used by the DMA.
	  This value depends on the maximum number of messages that will be sent
	  during a single transfer. 2KB guarantees enough heap size for sending 256
	  messages on a single transfer.
